(54) TORQUE CONTROL SYSTEM AND METHOD FOR VEHICLE MOTOR, MEDIUM, AND VEHICLE


(57) The disclosure provides a torque control system for a vehicle motor which includes: a target torque obtaining unit configured to obtain a target torque TRef of the motor that is associated with a vehicle pedal parameter; a compensated torque calculation unit configured to calculate a compensated torque TDmp of the motor; and a theoretical torque calculation unit configured to calculate a theoretical torque TCmd of the motor based on the target torque TRef of the motor and the compensated torque TDmp of the motor, the compensated torque calculation unit including an angular velocity acquisition module which is configured to obtain an actual angular velocity ωm of the motor that is sampled at a first frequency and an actual angular velocity ωl of a wheel that is sampled at a second frequency less than the first frequency and converted to a motor side.
